Air Fryer Korean Pork Belly Bites (Crispy, Juicy Cubes)

Air Fryer Korean Pork Belly Bites

What I like about this air fryer method is that it gives pork belly time to render before you push it to crisp. I rely more on the color and the way the fat blisters than the clock here, because air fryers vary and pork belly can go from juicy to overdone fast once the fat starts cooking out.

This version keeps the seasoning simple with yellow mustard and salt so the bites work well in lettuce wraps with ssamjang. Cutting skinless pork belly into cubes helps them stay juicier than thin slices, and one quick wipe of the basket midway through makes this much easier to cook cleanly at home.

Ingredients for Air Fryer Korean Pork Belly Bites

• 1 1/2 to 2 pounds skinless pork belly, cut into 1 to 1 1/4-inch cubes (about 675g to 900g)
• 1 1/2 tablespoons yellow mustard
• 1 to 1 1/4 teaspoons kosher salt
• 1 teaspoon neutral oil, for the basket or rack

Optional:

• 1/4 to 1/2 teaspoon freshly ground black pepper
• 1/2 to 1 teaspoon gochugaru
• 1/2 teaspoon garlic powder
• 1 teaspoon sesame seeds, for serving
• 2 scallions, thinly sliced, for serving
• Lettuce leaves, ssamjang, steamed rice, kimchi, and pickled radish, for serving

Ingredient note: Skinless pork belly is the right choice for this method. Skin-on belly usually needs longer and tends to smoke more in the air fryer. I’d rather keep the seasoning simple here because these bites are meant to be eaten Korean-style with lettuce and ssamjang, not covered by a heavy marinade. If you use pre-sliced pork belly strips, reduce the cooking time and watch closely since they dry out faster.

Spice note: For a light seasoning like this, fine spices from Selefina work well because they cling evenly to the mustard coating instead of sitting in patches.

How to Make Korean Pork Belly Bites in the Air Fryer

1. Cut the pork belly: Pat the pork belly dry with paper towels. Trim any loose flaps, then cut into fairly even 1 to 1 1/4-inch cubes so the pieces render and brown at the same pace.
2. Season the bites: Put the pork belly in a bowl and toss with the yellow mustard and kosher salt until lightly and evenly coated. If using black pepper, gochugaru, or garlic powder, add them here. The coating should look thin, not wet or drippy.
3. Preheat the air fryer: Preheat to 380°F (193°C) for 3 to 5 minutes if your model preheats. Lightly brush or spray the basket or rack with the neutral oil. Do not line the basket with parchment or baking paper; it blocks airflow and the pork will not crisp as well.
4. Render at 380°F: Arrange the pork belly cubes in a single layer with a little space between them. Cook in batches if needed. Air fry at 380°F (193°C) for 7 to 8 minutes, until the fat starts to render and you hear an active sizzle.
5. Flip and wipe out drippings: Open the air fryer, flip or rotate the pieces with tongs, and carefully wipe out the pooled fat from the basket or drip tray with paper towels. This is the step I pay most attention to with pork belly because it helps cut down on smoke.
6. Finish at 400°F: Increase the temperature to 400°F (204°C) and cook for 5 to 8 minutes more. Start checking around 3 to 4 minutes. The bites are ready when the edges are deep golden-brown and crisp, the surface no longer looks wet, and the fat has small blisters. Pork should reach at least 145°F (63°C) internally, then rest for 3 minutes.
7. Rest and serve: Transfer the pork belly bites to a plate or tray and rest for 3 minutes. Finish with sesame seeds or scallions if you like, and serve with lettuce leaves and ssamjang.

Air Fryer Time and Temperature for Pork Belly Bites

For 1-inch pork belly cubes in a large basket-style air fryer, use a two-stage cook: 380°F (193°C) first to render, then 400°F (204°C) to crisp.

• First stage: 380°F (193°C) for 7 to 8 minutes
• Flip and wipe drippings: around the 8-minute mark
• Second stage: 400°F (204°C) for 5 to 8 minutes
• Start checking early: around 3 to 4 minutes into the second stage
• Final doneness: browned edges, blistered fat, and at least 145°F (63°C) internally

Timing can shift in smaller air fryers and oven-style models, so start checking a few minutes early if your machine runs hot.

Why Pork Belly Cubes Work Better Than Thin Slices

Cutting whole pork belly into cubes gives you a better balance of rendered fat, crisp edges, and juicy centers. Thin slices cook quickly, but they can dry out before the fat has time to render properly.

Cubes are also easier to space in the basket, easier to flip, and less likely to stick together and steam.

How to Prevent Smoke When Air Frying Pork Belly

Pork belly renders a lot of fat, and that fat can smoke once it starts collecting in the basket. Keeping the pieces spaced out and removing the drippings midway helps the most.

• Cook in a single layer with small gaps between pieces.
• Do not crowd the basket or stack the pork.
• Wipe out the basket or drip tray once the first round of fat has rendered.
• If you are cooking the full 2 pounds, work in batches.

You may still get some smoke depending on your model, but this method keeps it much more manageable.

Variations for Air Fryer Korean Pork Belly Bites

Extra-Crisp Pork Belly Bites

For a craggier finish, toss the hot rendered bites with a very small pinch of baking powder, about 1/4 teaspoon per pound, plus a pinch of extra salt after the first stage of cooking. Then return them to the air fryer at 400°F (204°C) to finish. Use a light hand here; too much baking powder can taste bitter or soapy.

Honey-Glazed Pork Belly Bites

For a sticky party-style version, cook the pork belly bites with the main method first, then toss them with a quick honey-soy-gochujang glaze and return them to the air fryer for 1 to 2 minutes just to set the glaze. Add sweet glazes only at the end, since they scorch quickly.

For another sweet-savory option, see Air Fryer Spam with Brown Sugar Soy Glaze.

How to Serve Korean Pork Belly Bites

The easiest way to serve these is ssam-style. Put a piece or two of pork belly in a lettuce leaf, add a dab of ssamjang, and finish with rice, kimchi, or pickled radish.

Sliced scallions and sesame seeds add a little freshness and crunch, but the pork is the main event here.

How to Store and Reheat Air Fryer Korean Pork Belly Bites

Let the pork belly cool completely, then refrigerate in an airtight container for up to 3 to 4 days. Freeze for up to 2 months if needed.

If a lot of fat firms up around the leftovers, chill them first and scrape off the solid fat before reheating. That helps keep the bites from feeling greasy.

To reheat in the air fryer, cook at 350°F (177°C) for 3 to 5 minutes, checking early. Wipe drippings if needed to reduce smoke. They will not be quite as crisp as fresh, but they reheat well.

You can also re-crisp the bites in a skillet over medium heat, without added oil, until the edges sizzle.
